(AP) -- Heightened concern that Greece might fail to negotiate a deal with creditors to avoid defaulting on a looming debt payment weighed on U.S. stocks in midday trading Monday. The major indexes recouped some of their losses from earlier in the day as investors monitored the latest corporate deal news. Technology stocks were among the biggest decliners.
KEEPING SCORE: The Dow Jones industrial average was down 107 points, or 0.6 percent, to 17,790 at 12:28 p.m. Eastern Time. The Standard & Poor's 500 index fell eight points, or 0.4 percent, to 2,085. The Nasdaq composite fell 26 points, or 0.5 percent, to 5,025.
THE QUOTE: "All eyes, including our own, are on Greece," said Erik Davidson, chief investment officer for Wells Fargo Private Bank. "This is a grand experiment and if it were to go awry, it would certainly have implications."
GREEK DRAMA: Weekend negotiations on Greece's bailout terms produced no breakthroughs and Greek officials and creditors remained far apart as a deadline for a debt payment nears. Greek leaders want to get access to the final 7.2 billion euros ($8.2 billion) of their bailout program that's needed to repay debts and avoid a possible default that could trigger an exit from the euro; the bailout package expires at the end of the month.
